It’s not every day you get to spend a few seconds making pleasant chit-chat with one of the innovative pioneers of old-school hip-hop. Well, Tuesday, June 17, is one of those days, as virtuoso DJ GRANDMASTER FLASH visits Borders Buckhead tonight to sign his memoir, “Grandmaster Flash: My Beats, My Rhymes.” In addition to signing books, we’re sure Mr. Flash will answer questions about his adventures, his beats and, inevitably, his rhymes. The event starts at 7:30 p.m. 404-237-0707. www.borders.com.
